i excerpt the following from Richard Falk, writing on the Huffington Post.
As always in relation to the underlying conflict, some facts bearing on this latest crisis are murky and contested, although the American public in particular gets 99% of its information filtered through an exceedingly pro-Israeli media lens. Hamas is blamed for the breakdown of the truce by its supposed unwillingness to renew it, and by the alleged increased incidence of rocket attacks. But the reality is more clouded. There was no substantial rocket fire from Gaza during the ceasefire until Israel launched an attack last November 4th directed at what it claimed were Palestinian militants in Gaza, killing several Palestinians. It was at this point that rocket fire from Gaza intensified. Also, it was Hamas that on numerous public occasions called for extending the truce, with its calls never acknowledged, much less acted upon, by Israeli officialdom. Beyond this, attributing all the rockets to Hamas is not convincing either. A variety of independent militia groups operate in Gaza, some such as the Fatah-backed al-Aqsa Martyrs' Brigade are anti-Hamas, and may even be sending rockets to provoke or justify Israeli retaliation. It is well confirmed that when US-supported Fatah controlled Gaza's governing structure it was unable to stop rocket attacks despite a concerted effort to do so.
What this background suggests strongly is that Israel launched its devastating attacks, starting on December 27, not simply to stop the rockets or in retaliation, but also for a series of unacknowledged reasons. It was evident for several weeks prior to the Israeli attacks that the Israeli military and political leaders were preparing the public for large-scale military operations against the Hamas. The timing of the attacks seemed prompted by a series of considerations: most of all, the interest of political contenders, the Defense Minister Ehud Barak and the Foreign Minister Tzipi Livni, in demonstrating their toughness prior to national elections scheduled for February, but now possibly postponed until military operations cease. Such Israeli shows of force have been a feature of past Israeli election campaigns, and on this occasion especially, the current government was being successfully challenged by Israel's notoriously militarist politician, Benjamin Netanyahu, for its supposed failures to uphold security. Reinforcing these electoral motivations was the little concealed pressure from the Israeli military commanders to seize the opportunity in Gaza to erase the memories of their failure to destroy Hezbollah in the devastating Lebanon War of 2006 that both tarnished Israel's reputation as a military power and led to widespread international condemnation of Israel for the heavy bombardment of undefended Lebanese villages, disproportionate force, and extensive use of cluster bombs against heavily populated areas.
Respected and conservative Israeli commentators go further. For instance, the prominent historian, Benny Morris writing in the New York Times a few days ago, relates the campaign in Gaza to a deeper set of forebodings in Israel that he compares to the dark mood of the public that preceded the 1967 War when Israelis felt deeply threatened by Arab mobilizations on their borders. Morris insists that despite Israeli prosperity of recent years, and relative security, several factors have led Israel to act boldly in Gaza: the perceived continuing refusal of the Arab world to accept the existence of Israel as an established reality; the inflammatory threats voiced by Mahmoud Ahmadinejad together with Iran's supposed push to acquire nuclear weapons, the fading memory of the Holocaust combined with growing sympathy in the West with the Palestinian plight, and the radicalization of political movements on Israel's borders in the form of Hezbollah and Hamas. In effect, Morris argues that Israel is trying via the crushing of Hamas in Gaza to send a wider message to the region that it will stop at nothing to uphold its claims of sovereignty and security.
There are two conclusions that emerge: the people of Gaza are being severely victimized for reasons remote from the rockets and border security concerns, but seemingly to improve election prospects of current leaders now facing defeat, and to warn others in the region that Israel will use overwhelming force whenever its interests are at stake.
